| Outline of Final Research Achievements |
In this work, to prove the one-electron σ bond experimentally, electron-transfer reactions of cage compounds 1 were examined under various conditions.
In laser flash photolysis of 1b having tolyl groups, under photoinduced electron-transfer conditions, an absorption spectrum of the radical cation intermediate having a one-electron σ bond 1b･+ was observed successfully, as expected.
On the other hand, it was expected that 1d･+SbCl6-, a salt of a stable radical cation 1d･+ having a one-electron σ bond, would be produced in an electron-transfer reaction of 1d having the triphenylamine moiety by using aminium salt (4-BrC6H4)3N･+SbCl6- as a one-electron oxidant. In fact, however, a phenolate-ion containing salt 5d-Cl+SbCl6-, which is totally different from 1d･+SbCl6-, was unexpectedly produced in a high yield.
